Activation! Mazinger!

The beginning shows a wrecked Mazinger Z slumbering away from the Dark General. This will be the continuation of Episode 26, where the Dark General comes and Mazinger Z uses the Big Bang Punch to ram the Dark General. The story moves back to the very start of the events which lead to the previous episode. Kouji and his brother, Shiro, are living with their grandfather, Juzo, while mysterious murders occur around their manor. Investigating these murders is Inspector Ankokuji, who was also hired to be Juzo's bodyguard, while Dr. Hell and Baron Ashura prepare for their first attack on the Photon Power Lab. In the meantime, Boss and his gang kidnap Shiro in order to lure out Kouji and beat him. After Kouji fights Boss, Baron Ashura attacks his household with the gigantic robot known as "Talos", forcing Juzo to send out the Pilder to Kouji and Shiro. Moments later, Juzo activates the product of years of research: the Super Robot, Mazinger Z.
